The duplex is located on the 4th floor (no elevator). The bedroom is on the 2nd floor of the duplex, accessible via a spiral outdoor stairs. Toilet/shower are located on the living room floor (under the bedroom) so it can be a bit tricky if you need to use the toilet in the middle of the night (or early mornings). To get out of the bedroom you need to open up the curtains in order to open the door, if your partner (in case of couple) is still sleeping then it's quite inconvenience as you'll let the light in and can't really close the curtains when you're on the outside. The air con worked well and the shower was good.
